[Bug 1069908] Re: Ubuntu GNOME Remix image don't boot on EFI systems

[Tim]

I think we should keep secureboot, as per cjwatsons comments...

Looks like we should be right, just need to build iwth -updates enable
to ensure we get the updated ubiquity >= 2.12.15, which is an absolute
requirement for secureboot installations.

Title:
  Ubuntu GNOME Remix image don't boot on EFI systems

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  On EFI systems, the Ubuntu GNOME Remix image don't boot and we get
  this error message:

      error: file `/casper/vmlinux.efi.signed` not found.
      error: you need to load the kernel first.

  Also, looks like we miss some genisoimage parameters that will cause
  boot to fail at all on some EFI systems.
